Question

7.93 mol of c5h12 reacts with excess o2, how many moles of co2 will be produced by the following combustion reaction?

Answer 1

The following combustion of fuel will result in the production of 39.65 moles, claims the statement.

What is a mole, exactly?

A mole is 6.02214076 x 1023 of any chemical unit, including atoms, molecules, ions, and others. Due to the high number of electrons, molecules, or other components that make up any substance, the mole is a useful measure to utilize. The mole was initially defined as the quantity of atoms contained in 12 grams of co2, but the General Assembly on Measurement and Weights declared in 2018 that the mole will only contain 6.02214076 1023 of some scientific unit as of May 20, 2019.

Briefing:

C₅H₁₂+8O₂→6H₂O+5CO₂

From the equation, we see that 1 mole of C₅H₁₂ reacts with excess of O₂ to produce 5 moles of CO₂.

So, 7.93 moles of C₅H₁₂ will react with excess O₂ to produce (7.93*5) moles = 39.65 moles.
